About Tim Stivers Heating / Air Conditioning
Tim Stivers Heating / Air Conditioning operates from San Marino, California, delivering air conditioning repair services to residential and commercial clients across the Los Angeles metropolitan area. The business holds a perfect 5.0-star rating derived from two client reviews, reflecting consistent service quality in a competitive market. Established as an independently owned company, Tim Stivers Inc has built its reputation on thorough, well-planned heating and cooling solutions since the year 2000. The company maintains full state licensing and comprehensive insurance coverage, backing all workmanship with a 100% satisfaction guarantee.
What distinguishes this contractor is the depth of manufacturer relationships and the commitment to indoor air quality solutions beyond basic heating and cooling. As an authorized service provider for major brands including Lennox, Trane, Carrier, Rheem, Goodman, and American Standard, their technicians tackle repairs and installations across the spectrum of residential cooling equipment. The company offers advanced air purification technologies such as UV germicidal lights, whole-home air cleaners, and comprehensive duct system evaluation and sealing. This focus on IAQ (Indoor Air Quality) differentiates them from contractors who limit service to equipment repair alone. Additionally, their after-hours emergency availability addresses the urgent needs that arise during extreme temperature events.
Client feedback highlights the team's diagnostic precision and responsive service during challenging conditions. One reviewer described a scenario where the team arrived, identified the malfunction, and completed repairs before the homeowner experienced further discomfort during intense heat. The same review emphasized the technicians' polite demeanor and efficient work ethic. A second client succinctly characterized the company as superb with an excellent team, reinforcing the pattern of positive service encounters. These accounts demonstrate the contractor's ability to deliver timely solutions while maintaining professional client interactions.
What Customers Say
Both reviews award five stars, with one client specifically praising the team's diagnostic speed and polite demeanor during a same-day repair during extreme heat. The second reviewer uses concise language to characterize the company as superb with an excellent team.
